[mythtv-users] mythbackend

[Don]

Well, mythtv is running somewhat.
mythbackend gives this error:
[don at localhost bin]$ mythbackend
No setting found for this machine's BackendServerIP.
Please run setup on this machine and modify the first page
of the general settings.

Is there a setup program such as /usr/bin/setup or mythsetup.
I don't have one if there is.
mythfrontend works and when I go to the first page
of the general settings the only line I see that could have
anything to do with BackendServerIP is the first line for
hostname wich is localhost, the only hostname there is.

Does the backend need a different hostname?
